The geography that makes Utah one of the world’s most beautiful places also brings the nation’s dirtiest air in winter, when an icy fog smothers mountain valleys for days or weeks at a time. A group of doctors is declaring a health emergency over northern Utah's lingering pollution problem. Utah Physicians for a Healthy Environment planned to deliver a petition Wednesday demanding immediate action by elected officials. The group wants Gov. Gary Herbert and mayors of northern Utah cities to cut the pollution. (AP Photo/Rick Bowmer)
